Horror and mystery stories until issue #110 which featured the first appearance of Dr. Strange. The numbering for this series is also strange. After issue #168, the series was re-titled Doctor Strange (1968 series) and numbering ran from #169 to #183. To find that series, go to the letter "D" for Doctor Strange (1968 series). Then, in 1974, Marvel started the numbering over from #1 as "Doctor Strange (1974 series)". To find that series, also go to the letter "D". At the same time in 1974, Marvel restarted publishing Strange Tales, beginning at #169 and continuing through #188. Those issues are found here. The Nick Fury stories of issues #146 to #155 were reprinted in "S.H.I.E.L.D."
